INTRODUCTION

...............................................................................................................................................................................................................

Introduction By means of the transit times of ultrasonic pulses, the USZ 08 ultrasonic flowmeter measures the flow velocity of the gas from which it calculates the flow rate at measurement conditions. Here use is made of the fact that ultrasonic pulses move faster in the direction of flow than in the opposite direction.

1

S1

v D

 L

S2 The transit times from S1 to S2 and from S2 to S1 are calculated as follows:

t S12  where:

v: c: : L: 0

L c 0  v  cos 

t S21 

L c 0  v  cos 

mean flow velocity velocity of sound path angle to the pipe path length

If measurements are taken alternatively in both directions, the velocity of sound depending on the type of gas is no longer included in the calculation of the flow velocity: v

 1 L 1      2  cos   t S12 t S 21 

In order to take the flow profile into account, the USZ 08-6P takes measurements with a total of six acoustic paths in three planes. In the case of the 3-path design of type USZ 08-3P, the two paths of each plane crossing each other are replaced by one V-path with single reflection.

...............................................................................................................................................................................................................

Manual USZ 08 · EN04 · 2013-06

INTRODUCTION

...............................................................................................................................................................................................................

For non-fiscal metering also the 2-path design of typ USZ 08-2P can be used. This version is equivalent to a reduced 6-path design, which only has the two acoustic paths in the middle plain.

Signals are evaluated by the USE 09(-C) ultrasonic electronic system which is installed on the meter case. As a result, the flow velocity is determined for each acoustic path from the transit times measured.

2

There are the following two variants of the ultrasonic electronic system available: 1. USE 09 - Meter without display in the meter head - PTB-approved - Basic version for digital connection to the ERZ 2000 USC Every ultrasonic flowmeter relies on an ERZ 2000 USC to calculate the flow velocity averaged through the pipe diameter from the data of the individual paths. The readings of the volumes at measurement conditions for forward and reverse flows can also be taken at the computer.

2. USE 09-C - Meter with electronic totalizers - MID-approved - Full version of the USE 09 with integrated controller function With this configuration, it is possible to evaluate even flow rate and totalizer readings without an ERZ 2000 USC; other types of correctors can be connected via pulse outputs.

Using a PC, you can access the USE 09(-C) data via a service interface. To do this, you can use the RMGView diagnostic software.

The USZ 08 ultrasonic flowmeter is to be operated with an inlet pipe and an outlet pipe. The following details are identical to the requirements of the PTB approval certificate and are therefore binding for custody transfer metering. These specifications are also recommended for secondary metering; if they are not observed, it is likely that the accuracy of measurement will be lower.

The inside diameters of the inlet and outlet pipes may be up to 2% smaller or up to 5% larger than the inside diameter of the meter.

Combination with the WBZ 08 vortex meter In the case of nominal diameters from DN 200 to DN 600, a 6-path ultrasonic flowmeter can be installed upstream of a WBZ 08 vortex meter so that it forms a part of the inlet pipe of the vortex meter.

Outdoor installation In case of outdoor installation of an USZ 08 with viewing window and electronic display, a cover for the electronics case is required. The display must definitely not be exposed to direct solar radiation, since otherwise it will be destroyed by UV radiation!

Ultrasonic flowmeters can be equipped with a cover in the factory. Also retrofitting on site is possible.

Seals It must be guaranteed that flange seals of RMG turbine meters do not protrude from the flange into the gas line.

All seals approved as per DVGW can be used depending on the requirements for stability and reliability.

14

We recommend seals with the following maximum material characteristic values according to the AD2000 rules: − gaskets: k0 x KD = 20 x bD | k1 = 1.3 x bD [N/mm] − grooved seals: k0 x KD = 15 x bD | k1 = 1.1 x bD [N/mm] k0 x KD = 50 x bD | k1 = 1.4 x bD [N/mm] − spiral seals: − octagonal ring joint seal: KD = 480 N/mm2 For recommended dimensions, see the tables below.

If the meter is operated in conjunction with a Flow Computer/ultrasonic computer of the ERZ 2000 USC series, the computer is to be connected to the RS 485 1 interface. Due to the fact that the parameters of the meter are stored in the ERZ 2000 USC, you have to make sure that the correct computer is connected to the measuring element (compare the serial numbers of the measuring element on both data plates). ...............................................................................................................................................................................................................

...............................................................................................................................................................................................................

The RS 485 0 interface is used for servicing. The RMGView service and diagnostic software which is required for this purpose is described from page 35 onwards.

A second Flow Computer can optionally be connected to the RS 485 2 interface if an appropriate optional USE 09 card is used. However, this interface can also be used as a Modbus (ASCII or RTU) interface for other purposes.

On the USE 09-C, there are 2 pulse outputs (terminals 7/8 and 9/10) and a current output (4-20 mA) available. The pulse outputs are set in such a way that a frequency of approx. 2 kHz is outputted at maximum flow rate. The direction of flow can be outputted through the contact outputs I/O1 and I/O2.

17

Use shielded cables from a length of 1 m (this also applies to power cords). Apply the shields to the cable glands. Use cables which are twisted together in pairs of the type LiYCY 2x2x0.75 mm虏 for the data line!

Die maximum permissible cable length between USZ 08 and ERZ 2000 is 500 m.

Start-up

20

After the meter has been installed and the ERZ 2000 USC has been connected, the parameters of the meter have to be checked on the computer. They are listed on the verification certificate of the meter together with the coordinates. Parameters from the verification certificate without any coordinate stated are directly stored in the ultrasonic electronic system of the measuring element (IGM/USE 09). They can be found on the inspection certificate of the measuring element and can be checked using the RMGView diagnostic software. In the case of a meter without an ERZ 2000 USC, all parameters are programmed into the ultrasonic electronic system on the test facility and it is not necessary to check them.

As soon as the meter is pressurized, it is possible to check its function. To do this, check the velocities of sound measured for each path (lines 9 to 14) in column FH (Ultrasonic diagnosis) on the ERZ 2000 USC. The velocity of sound varies with the gas composition, pressure and temperature. The values of the individual paths should differ only slightly. However, a comparison with the velocity of sound of the fluid can be made only to a limited extent, since such velocity of sound can be determined only in a very inaccurate way under operating conditions.

If there is no flow rate available during start-up, thermal layering may occur in the piping, so that the velocities of sound of the paths of different measuring planes may differ considerably from each other.

If there is no ERZ 2000 USC available (model with totalizer on the meter case), the velocities of sound (columns L to Q) can be read out using the RMGView software.

If the velocity of sound of a device with an ERZ 2000 USC should not be plausible, it is necessary to perform troubleshooting using RMGView.

If the velocities of sound of the measuring element are OK, but not on the ERZ 2000, this is in most cases due to the connection between the measuring element and the computer. In such a case, check not only the cable but also the screening and earthing as well as the terminating resistor on the ERZ 2000 USC. If only a single path has failed, it is likely that the fault is to be found in the wiring of the path.

Operating the ultrasonic computer General information about the ERZ 2000 USC Overview of functions Depending on the software installed, the ERZ 2000 device family is equipped with an integrated functional unit for direct connection to the ultrasonic measuring element (called IGM for Industrial Gas Meter in the software). To operate the IGM, no further hardware is required. The function is always active, but has to be initially enabled in the factory to ensure trouble-free operation. If it is not enabled, a fault message will permanently be outputted and the disturbance totalizers will be used for metering. Connection to the measuring element is to be made via the COM 1 port in RS 485 mode. Modbus is used for communication with the measuring element.

The DZU operating mode (15) requires another functional unit (remote unit) to be interconnected between the measuring head and the volume corrector. This is either the external USZ 9000 remote unit which represents the main totalizer from the point of view of custody transfer metering or the USE 09-C ultrasonic electronic system with an integrated controller and main totalizer. The DZU protocol transmits meter readings, flow rates and status information for diagnostic purposes. In the case of the ERZ 2000, a USZ 9000 is to be connected to the COM 2 interface ("DZU" mode, 9600 baud); a USE 09-C is to be connected to the COM 1 interface ("DZU" mode, 19200 baud).

DZU: ERZ 2000 with USE 09-C ultrasonic flowmeter control unit If you choose this mode, the FH ultrasonic flowmeter diagnosis function is of importance. Here the following information will be shown: The average velocity of sound measured, indication of the unit, gas velocities of paths 1 to 6, velocities of sound of paths 1 to 6, AGC (automatic gain control) levels for upstream and downstream directions, measurement qualities 1 to 6 (= indication of valid measurements in percent), alarm statuses, and the representation of messages of the USE 09-C. Functions from the operating modes with pulse input continue to be active and are used appropriately. These functions include the following: Starting up and shutting down a plant: Start-up is trouble-free if qm passes the range from the creeping quantity limit to the lower alarm limit during start-up and slow-down. An alarm is generated if qm is still below the alarm limit and above the creeping quantity limit after the start-up or slow-down time has been exceeded. An alarm is defined as going when the lower alarm limit is passed (when the plant is started up) or when the creeping quantity limit is passed (when the plant is shut down).

Start-up/slow-down time: There is a separate "Start-up/Slow-down" chapter to be found under the <9> Meter key. Here you can see the momentary state, the current start-up and slow-down times and the parameters for the start-up and slow-down times.

Start-up and slow-down times are parameters for the time monitoring of the lower flow rate limit qmmin. The qmmin alarm is not triggered until one of these times has elapsed. These parameters are important for the start-up and slow-down phases.

Creeping quantity limit: The Vm and Vb totalizer readings are not increased as long as the flow rate at measurement conditions is below the creeping quantity limit.

Creeping quantity mode: There are the two following options: Do not use ("discard") the creeping quantities occurred.

Use the creeping quantities occurred and add ("accumulate") them to normal quantities.

USZ effect of fault: It is shown whether USZ protocol errors (DZU protocol) are signalled as an alarm or warning or whether they are not signalled. This depends on the operating mode selected.

Error curve linearization of volume metering when using the USE 09-C The error curve linearization of the gas meter can optionally be performed using three different methods.

Error curve linearization with polynomial related to the flow rate Error curve linearization with polynomial related to the Reynolds number

25

Error curve linearization using the interpolation point method

These methods are identical to the methods used in the case of turbine meters.

For further descriptions of the different methods, please refer to the basic manual.

ID data of the ultrasonic electronic system of the measuring element of type USE 09 (pre-configured for up to 8 paths) As with the USE 08 predecessor version comprising three modules of type IGM for two paths each, two paths each are assigned to an imaginary IGM in the case of the USE 09 too.

FH Ultrasonic flowmeter diagnosis This function is provided not only for indicating diagnostic values when connecting the USE 09-C, but also for the ERZ 2xxx USC types; here, however, only fields 3 to 32 with gas velocities of paths 1 to 6, velocities of sound of paths 1 to 6, AGC levels for upstream and downstream directions, and the measurement quality (= indication of valid measurements in percent). The representation for 6 paths has been adapted to the USZ 08. For more detailed information about the individual paths, see columns HN to HU (see page 31).

Number of measured values used to calculate replacement values. Here a coefficient matrix is formed which is used to reconstruct a failed path by means of a replacement value.

The higher the number parameterized here, the better the replacement value obtained, but the longer the determination process. Therefore, we would recommend choosing a small number on start-up to obtain reasonably useful replacement values as soon as possible.

Path velocities below this limit will be disregarded. Parallel to this, you can also set the creeping quantity limit. However, please note that zero-point noise has the higher priority. This means, that suppressed quantities are not included in the flow or totalizer calculation and are already eliminated for creeping quantity parameterization.

To ensure correct flow rate calculation, you must enter the precise inside diameter of the meter in coordinate GB-55 (nominal diameter). You can find this information in the annex to the verification certificate. From software version 1.5 upwards, this value can no longer be found in GB-55, but has to be entered in GA-08 (pipe diameter).

In IGM mode, there are three polynomials for correction: GM Reynolds number correction, GN base correction, GO error curve linearization.

All the other polynomials and interpolation point methods are switched off. The parameters are calculated in the factory.

Current measurement quality as reported by the sensor system. The measurement quality can be in the range from 0 to 100 percent. The minimum measurement quality expected can be set in GI 07 Measurement quality. If the measurement quality falls short of this value, the path will be deemed to have failed.

Fatal errors will immediately reduce the quality to 0%.

Syntactical errors will reduce the quality by 20%.

A noise is expected regarding the measured values. If the sensor system successively transmits the same set of measured values, quality will be reduced by 12 percent.

Every single communication primitive failed will reduce quality by 1%. There are 15 primitives per path and correction cycle, so that in the worst case the total effect can be 15% per path and corrector cycle.

With each correction cycle, quality will be reduced by 1%.

This will result in a general trend towards deterioration taking unknown or unconsidered cases into account.

Every perfectly performed total communication cycle (of all paths) will lead to an improvement in quality by 10%.

The minimum communication quality expected can be set in GI 08 Communication quality. If the communication quality falls short of this value, the path will be deemed to have failed.

Acknowledging alarm and warning messages and events Functioning of alarm and warning messages Warning and alarm messages are indicated by a yellow (warning) or red (alarm) LED on the front panel of the device. The warning relay or alarm relay closes parallel to this.

The active message is indicated by a flashing LED. If the message goes, the LED will turn to steady light. If there is more than one message at the same time, the flashing light prevails. For univalent messages, there is only the state "Message is active". No coming or going is indicated, and therefore, the active state of these messages is retained until they are acknowledged.

The warning or alarm relays pick up as soon as a message comes and release again if all messages are gone. In the case of univalent messages, the relays remain picked up until the messages are acknowledged.

35

Warning and alarm messages have to be acknowledged by pressing the Alarms key ( ! ).

All messages which have not been acknowledged will be displayed. If there are no more events, the following text will appear: "no error".

The following messages are displayed on the ERZ 2000 USC, the messages from the ultrasonic electronics USE 09 in the measuring element are listed in the section "Alarm and warning messages USE 09".

RMGVIEW DIAGNOSTIC SOFTWARE

...............................................................................................................................................................................................................

RMGView diagnostic software Functions The RMGView diagnostic software allows the USE 09 measuring electronic system to be directly accessed with a PC. The program provides the following features:  Reading out all available data from an ultrasonic flowmeter using the USE 09.  Automatic detection of the USE 09 software version.  Displaying measured values and parameters as a list.  Password-protected editing of the USE 09 parameters.  Displaying measured values as a graphic.  Creating user-defined lists (e.g. for test certificates).  Creating user-defined graphics.  Parameterizing the USE 09 (with open calibration switch).

37

Installation System requirements The program runs on all Windows versions from Windows 98 upwards.

Requirements for speed, RAM and hard disk memory are low.

You need a serial interface to connect the USE 09. You can use standard COM interfaces and USB interfaces; however, you need an interface converter for RS 485 to RS 232 or USB.

Installing the program If you install a new version of RMGView, it is not necessary to uninstall its predecessor version.

If you have received the program by e-mail, unzip the attached zip file. Start the RMGViewInstaller(version number).exe installer.

If you have received the program on a CD, the CD should automatically start when you insert it into the CD drive. Otherwise, navigate to the CD directory and start the RMGViewInstaller(version number).exe installer.

The installer will guide you through the further installation process.

When you start the program for the first time, you will possibly have to set the Modbus parameters in menu item "Settings,Modbus": select the COM port, baud rate: 38400, bits-parity-stop bits: 8N1, Modbus address: 1.

USE 09 MEASURED VALUES AND PARAMETERS

...............................................................................................................................................................................................................

USE 09 measured values and parameters Access Using the RMGView diagnostic software, you can display and, if necessary, also edit all measured values and parameters of the USE 09 ultrasonic electronic system. However, you have to distinguish whether you want to use the controller functions of the USE 09-C or of the ERZ 2000 USC.

39

USZ 08 without the ERZ 2000 USC Flow Computer All the parameters listed below will be visible on the display of the USE 09-C and will be used to calculate the flow rate.

USZ 08 with the ERZ 2000 USC Flow Computer The parameters of the controller function are stored in the ERZ 2000 USC which, in this configuration, fulfills the tasks of the ultrasonic control computer. Furthermore, using RMGView you can display the whole matrix; however, the parameters in the columns of the controller function are of no significance. These are in particular the columns identified by the "USE 09-C" addition. These are hidden in the display of the USE 09 which is optionally available.

List of measured values and parameters The following tables show the parameters which can be displayed or edited using the RMGView diagnostic software. The coordinate shown in the left column corresponds to that displayed in RMGView. In the case of different device software versions, individual parameters may have different coordinates.

The second column shows how the individual values are protected: A: Display values which cannot be changed.

C: User data which can be changed via the user code.

E: Custody transfer metering data which can only be changed if the calibration switch is open.

F: Free parameters without protection.

S: Specially protected parameters which can only be changed via the user code and the calibration switch.

In the case of some values the units are variable depending on the setting in the Mode column (Y).

These values are identified by "&": &v: m/s or ft/s (flow velocity) &Q: m³/h or acfh (flow rate) &P: P/m³ or P/cf (pulse factor) &Z: m³ or acf (totalizers) The column to the right of the Modbus address shows the data type.

Brief description of the USE09 Modbus Parameterizing Modbus

56

The USE09 has three serial interfaces: - interface – 0 is reserved for servicing (RMGView).

- interface – 1 has been designed for exchanging data with volume correctors.

- interface – 2 (optional) is intended for communications with a Modbus master.

The interface and Modbus parameters can be set in the "Serial ports" column.

Interface – 2 can be configured as RS232 or RS485. Such configuration is to be made via the software and the hardware.

BRIEF DESCRIPTION OF THE USE09 MODBUS

...............................................................................................................................................................................................................

Special features of the USE09 Modbus:

58

- All data types comprising more than one register can only be written completely. float (F) : 2 registers double (D) : 4 registers long integer (L) : 2 registers integer (I) : 1 register Text (T) : 10 registers The data types are to be found in the tables of the "USE 09 measured values and parameters" chapter in the column standing to the right of the Modbus address.

- Text fields must at least have one final null (0x00). Max. text length is 19 characters.

- Modbus registers are the registers transmitted through the bus – therefore, no registers +- 1!

In any case, a register offset can be set in the USE09.

- In the tables with the measured values and parameters for the individual paths, there are the Modbus addresses for path 1; the addresses for paths 2 to 8 follow directly afterwards.

Example: The velocity of sound for path 1 has address 6020. Since it is a quantity in the float format, the address for path 2 is 6022 and the velocity of sound for path 6 is to be found under address 6020 + 5 * 2 = 6030.

Please contact RMG Messtechnik to obtain the complete Modbus register assignments for the USE09.
